drm/panel: novatek-nt35950: fix return value check in nt35950_probe()

2024-12-27T12:58:52+00:00

[ Upstream commit f8fd0968eff52cf092c0d517d17507ea2f6e5ea5 ] mipi_dsi_device_register_full() never returns NULL pointer, it will return ERR_PTR() when it fails, so replace the check with IS_ERR().

[ Upstream commit 9dfc46c87cdc8f5a42a71de247a744a6b8188980 ] The current measured frame rate is 59.95Hz, which does not meet the requirements of touch-stylus and stylus cannot work normally. After adjustment, the actual measurement is 60.001Hz. Now this panel looks like it's only used by me on the MTK platform, so let's change this set of parameters.

drm/panel: boe-tv101wum-nl6: Check for errors on the NOP in prepare()

drm/panel: himax-hx8394: Handle errors from mipi_dsi_dcs_set_display_on() better

2024-08-03T06:53:46+00:00

[ Upstream commit cc2db2ef8d9eebc0df03808ac0dadbdb96733499 ] If mipi_dsi_dcs_set_display_on() returned an error then we'd store that in the "ret" variable and jump to error handling. We'd then attempt an orderly poweroff. Unfortunately we then blew away the value stored in "ret". That means that if the orderly poweroff actually worked then we're return 0 (no error) from hx8394_enable() even though the panel wasn't enabled. Fix this by not blowing away "ret".
